Variety
The metagame should have the widest possible variety of playing options and strategies that are viable and competitive for knowledgeable players.
Explanation:
As they say, "Variety is the spice of life". And nowhere is that more true than in the world of gaming. Game makers discovered long ago that players crave diversity, change, and improvement. That's why most successful games are very broad, and are constantly adding new elements. For this reason, a high-quality metagame should be inviting to a wide number of people and personalities. By constantly striving for maximum variety, we can maximize the potential player base, which has the inevitable effect of increasing the number of good players, good strategies, and overall quality of competition. A varied metagame is fresh and exciting, and provides a constant source for investigation and discovery.
If we limit variety, or allow it be reduced, we effectively "shrink" all aspects of the metagame. A game with limited variety is boring to all but the most diehard participants. In a low-variety metagame, the best playing strategies become widely known and predictable, and participation wanes. For this reason, we should constantly strive for as much variety as possible. And, when limits to variety become apparent, the limits should be removed, if possible.
Issues and Concerns:
- Too much variety is chaos.
- Variety without quality is useless.
- No one can master a game with too many options
- "Wide" is sufficient, not "widest"
- How knowledgeable should players be?
Other Comments:
This characteristic is typically underlying arguments about "centralization", or when people complain about the game being "boring".
